Patent DE-2652826-A1 (DE)
Title: Tape control for endless projection cassette - with inner turns curved towards reel centre for even pitch
Inventor: STACHE KNUT
IPC: G03B21/32
Filed: 1976-11-20
Abstract: The endless projection cassette has a special reel centre which allows the inner turns of the film or tape to bend into the centre. This ensures that the amount of tape per turn is even from the centre turns to the outside turns. Typical reel centres are star shaped. The constant tape length per turn eliminates the successive turns rubbing over each other and damaging the film or tape. It simplifies the tape guidance control. The system can be applied to conventional cassette shapes.

Title: Indirect measurement of respiratory gases compsn. - uses measurements monitored during deep expiration compared with predetermined threshold concentration
Inventor: KIRMAIER NORBERT DR ING
IPC: A61B5/083
Filed: 1977-09-05
Abstract: Exhaled gases are analysed and the gas components evaluated in the area of the saturation concentration. This saturation concentration is only achieved at the end of a prolonged and deep expiration and this is ensured, without a knowledge of the respiratory volume, by monitoring the increasing gas concentration, comparing it with a predetermined value and ending the measurement when the value is exceeded. Hence the amplified signal from the gas sensor is applied alternately to two stores, under the control of a clock. The difference is formed and compared with a predetermined level.

Title: IC engine with low emission of nitrogen oxide and hydrocarbon(s) - has large precombustion chamber with controlled initiation of fuel injection
Inventor: KARABA ALBERT M
IPC: F02D21/08
Filed: 1978-10-30
Abstract: The low-emission IC compression ignition engine has a pre-combustion chamber communicating with the cylinder near the top. Low emissions of NOx are achieved by constructing the pre-combustion chamber to have a volume of between 70% and 85% of the combined pre-chamber and main combustion chamber volume when the piston is at top dead centre, and by variably controlling the initiation of fuel injection into the pre-combustion chamber. Initiation of fuel injection occurs between 5 deg. crank angle before TDC and 20 deg. crank angle after TDC.
